[PATCH 5.4 112/388] nfsd: Fix a perf warning

[Greg Kroah-Hartman]

From: Trond Myklebust <trondmy@xxxxxxxxx>

[ Upstream commit a9ceb060b3cf37987b6162223575eaf4f4e0fc36 ]

perf does not know how to deal with a __builtin_bswap32() call, and
complains. All other functions just store the xid etc in host endian
form, so let's do that in the tracepoint for nfsd_file_acquire too.
